Critical Mass
Funky Monkey. Sweati Yeti. Ball Shrinker. Death March. The only thing more impressive than the names of the obstacles in the Tough Mudder racing series are the number of athletes willing to subject themselves to their torture: 180,000 this year alone. 鈥淲e bill ourselves as Ironman meets Burning Man,鈥 says Tough Mudder founder Will Dean, a former counterterrorism officer in the UK. 鈥淓ndurance sports don鈥檛 have to be boring.鈥 Indeed, in the past five years, adventure races and their old-school 颅endurance cousins, marathons and triathlons, have morphed into amenity-laced parties. There are pre-race meals at Tavern on the Green (New York City Marathon), in-race live music (Austin 颅Triathlon), and post-race parties with barbecue feasts and knife-throwing contests (Warrior Dash). And the best reason to sign up? They鈥檒l break you out of your fitness rut in a way that Crossfit, P90X, and Zumba never will. Just take our crash course in each discipline, then select an event from our list of favorites. Suffering shouldn鈥檛 be this much fun.
Marathons
Running On

Costume Contests

Call it the comfort factor: as marathons have moved into the mainstream, organizers have added perks, everything from swag bags to massages. Many races now resemble 26.2-mile bacchanals as much as competitions: in-race entertainment, extravagant post-race dinners (on a cruise ship, in the case of the Miami Marathon), and costume contests. Nowhere is that trend more evident than in the Rock 鈥檔鈥 Roll Marathon Series, where runners are treated to live 颅music and after-parties at events from 颅Seattle to Savannah. At the Rock 鈥檔鈥 Roll San Diego Marathon, there鈥檚 a live band every mile of the course. The festive atmosphere is one reason the series has added 25 races since it started in 1998 and now has more than 300,000 people competing in events around the globe. But no matter how many bands they pack into the course, it鈥檚 still a marathon, and there鈥檚 just no way to make 26.2 miles easy. 鈥淚t鈥檚 not an event you can cram for,鈥 says Terrence Mahon, coach of U.S. record holder Deena Kastor. 鈥淪uccessful training is about consistency.鈥 His tip for race day? 鈥淭he big颅gest mistake I see runners make is going out too fast. The first part should feel easy, but that doesn鈥檛 mean you should go faster.鈥

Best Race for Running with Diddy:
New York City Marathon

Triathlons
Triple Play

During its first three 颅decades as a sporting event, the 颅tri颅a颅thlon suffered from an image problem. Ironman races鈥斅2.4-mile swim, 112-mile bike ride, 26.2-mile run鈥攇ot all the 颅attention, and the triathlon was considered by most to be a fringe pursuit for type A endurance freaks. But in the past ten years, the number of sprint-distance races鈥攖ypically a half-mile swim, 12-mile bike ride, and three-mile run鈥攈as exploded, so 颅tackling your first event is easier than you might think. 鈥淭he intensity level really varies,鈥 says USA Triathlon CEO Rob Urbach. 鈥淭oday there are races for all types of people.鈥 What鈥檚 more, triathlon training is, by definition, cross-training, so prepping for your first event will bring variety to your work颅out routine. 鈥淚t adds new 颅chal颅lenges,鈥 says Urbach. 鈥淎nd the sports help balance each other out, allowing people to stay healthy and interested for a much longer period of time.鈥
